Expression of ZEB2 in hyperoxia-exposed lung tissue. Neonatal rats were exposed to normoxic or hyperoxic conditions for 14 days; hyperoxia exposed rats were subsequently injected with shRNA-NC or shRNA-PLGF. (A) Western blot analysis and (B) quantification was performed to determine ZEB2 protein expression levels in rat lung tissues; β-actin was used as the endogenous control. Data are presented as the mean ± standard deviation. n=8. **P<0.01. (C) ZEB2 mRNA expression levels were detected by reverse transcription-quantitative PCR. Data are presented as the mean ± standard deviation. n=3. **P<0.01. NC, negative control; PLGF, placental growth factor; shRNA, short hairpin RNA; ZEB, zinc-finger E-box binding homeobox 2.
